Heat Pipe Collector Systems
Based on their hydraulic properties, HP collectors are able to be integrated with an angle of 20-90° on any building ( pitched roof, facade or even free standing). The s-power HP collectors are used for solar drinking water, pool heating, furnace support and process heat. Under the influence of the heat, the liquid which is inside the Heat Pipe evaporates and the vapor erases into the condenser. In order to limit the temperature, the s-power HP vacuum tubes do not have a valve in their construction. Even in stagnation, the temperature on the condenser head does not rise above 160°C. This serves as a self-security system for the s-power HP collectors. All vacuum tubes are axial adjustable towards the sun and due to their dry connection they can be individually exchanged even during operation. The innovative plug-in connection system of the tubes allows them to be fast and securely assembled inside the header.
Their modular concept allows the collectors to be fast and easy installed onto the building.The s-power HP (Heat Pipe) collectors are „real“ all seasons systems with exceptional yearly solar earnings (kW/m²/a). They therefore set new standards in the area of diffuse irradiation. The one-of-a-kind anti-reflexcoating (nano-coating) applied onto the inner and outer side of the glass tube allows for an extraordinary high light transmission (~97%), a very low light reflection (~3%) and therefore outperforms all standards so far. The high performance-copper-absorber, which is coated with Titan-Nitrid-Oxide (TINOX), absorbs the sunlight highly effective. (~96%). The absorber is welded onto the heat-carrier-pipe using ultrasound-welding. The patented, innovative glass-metal connection grants for highest quality measures (10 years warranty by the manufacturer). The glass-metal connection seals the glass tube to preserve the high-performance-absorber-unit enduringly under a vacuum of 10-5mbar (100% Insulation).
